Just days after Crystal, 25, called off her wedding to Playboy honcho Hugh Hefner, she decided to capitalize host a pool party at Las Vegas’s Wet Republic, much to the dismay of Holly Madison who slammed her on twitter.

“That’s a new low,” tweeted Hef’s ex Holly of Crystal’s decision to host a party on her would be wedding day. “That’s disgusting and whoever booked her is tacky,” added Holly.

When someone tweeted on whether or not a film crew would be around to film Crystal’s pool party, Holly responded with this tweet – “Trust me, NO ONE is interested in filming Crystal! She left Lifetime high and dry while filming a 2 hour special!” Holly is referring to a deal Crystal and Hef had with the Lifetime network to air a special on their wedding.

As for Crystal, she did not respond to Holly’s criticism directly, instead choosing to retweet a fan’s message to her. “Its cool that ur being WAY classier than Holly by behaving civilized & never speaking badly about her, even though u could! @CrystalHarris,” was the message retweeted by Crystal.

And in an interview with PEOPLE, Crystal attempted to shed some light on her controversial decision to party this Saturday. “I’m doing okay,” said Crystal. “I just had to get away. Today is the day and I just had to get away. I’m going back tonight so I just wanted to get away for the day.”

Crystal insists Hef is not heartbroken citing he has a lot of other women to keep him company. “It doesn’t make sense to have so many women around but still have a marriage,” she said. “It doesn’t make sense, so it was the right thing. I wasn’t the only woman in Hef’s life and it wasn’t going to stay that way after the marriage.”

When it comes to the linking up with famewhore Heidi, sources close to Crystal reveal Heidi reached out to her following the break up and invited her to co-host the party. . Meanwhile it appears Hef and Crystal remain cordial. Hef tweeted over the weekend, “Crystal came by to see how I’ve been doing. We remain close friends.”
